Summary of Colorado (CO) Driver Handbook 2026

The Colorado Department of Revenue Division of Motor Vehicles (DMV) oversees driver licensing and vehicle registration. Any person moving to Colorado must apply for a state driver license within 30 days of establishing residency, and all licensed drivers must notify the DMV within 10 days of any address change. A standard noncommercial Class R driver license permits operating passenger cars, vans, and pickup trucks.

Colorado enforces a Graduated Driver Licensing (GDL) program for minor drivers. An Instruction Permit can be issued at age 15 with driver education, age 15½ with a driver awareness course, or age 16 without formal education. Minor drivers under 18 holding a permit must log 50 hours of supervised driving (including 10 hours at night) and hold the permit for at least 12 months before obtaining a minor driver license. Minor drivers are subject to strict GDL restrictions: no passengers under age 21 for the first six months (excluding family), no more than one passenger under 21 for the next six months, a driving curfew between 12:00 midnight and 5:00 a.m., and mandatory seat belts for all passengers.

Obtaining a Colorado driver license requires passing vision, written knowledge, and practical driving tests. The mandatory vision screening requires a minimum visual acuity of 20/40 in at least one eye with or without corrective lenses. The state knowledge exam consists of 25 multiple-choice questions based on the driver handbook, requiring a minimum passing score of 80 percent (20 correct answers).

The practical road skills test evaluates essential driving maneuvers, including parallel parking within 18 inches of the curb, three-point turns, smooth stopping, lane changes, and intersection navigation. Applicants must provide a safe, properly registered, and insured vehicle equipped with operational seat belts, turn signals, brake lights, horn, windshield wipers, and tires with at least 2/32-inch tread depth.

Conducting a thorough pre-trip inspection and adjusting controls ensure safe vehicle operation prior to entering traffic. Drivers should verify that headlights are visible from at least 500 feet, the horn is audible from 200 feet, and mirrors provide an unobstructed view extending 200 feet to the rear.

Proper posture and hand positioning provide optimal vehicle control during emergency maneuvers. Drivers should keep their hands positioned at 9 o'clock and 3 o'clock or 8 o'clock and 4 o'clock on the steering wheel using push-pull or hand-over-hand steering. Seat belts are mandatory for all front-seat occupants and all passengers under 18 years of age.

Colorado statutory speed limits establish maximum legal speeds under ideal driving conditions: 20 mph in active school zones, 30 mph in residential districts, 40 mph on open mountain highways, 55 mph on rural two-lane highways, and 65 to 75 mph on rural interstate highways. Colorado's basic speed law requires driving at a safe, prudent speed for existing road, weather, and traffic conditions regardless of posted limits.

Maintaining proper space management provides vital reaction time. Motorists should maintain a minimum three-second following distance under normal conditions, expanding to four or more seconds in snow, ice, fog, rain, or when following motorcycles or heavy trucks. Turn signals must be activated at least 100 feet before turning in urban areas and at least 200 feet before turning on four-lane highways where posted speeds exceed 40 mph.

Traffic control signals, signs, and pavement markings regulate right-of-way and communicate critical hazards. A steady red signal requires a complete stop; right turns on red are permitted after a complete stop unless posted otherwise. A flashing red signal functions as a stop sign, while a flashing yellow arrow permits turns only after yielding to oncoming traffic and pedestrians.

Standardized sign shapes communicate legal instructions: octagons indicate a mandatory stop, inverted triangles signify yield, pennants on the left side of the road mark no-passing zones, and diamonds warn of upcoming hazards. On the road surface, solid yellow lines separate opposing traffic and prohibit passing, while broken yellow lines permit passing when safe.

Navigating intersections safely requires adhering to established right-of-way rules. Drivers must yield to traffic already in an intersection and yield to the vehicle on the right when arriving at an uncontrolled multi-way intersection simultaneously. Vehicles entering a roundabout must yield to traffic already circulating within the roundabout.

Parking regulations prohibit stopping or parking within 15 feet of a fire hydrant, 20 feet of a crosswalk, 30 feet of a stop sign or signal, or 50 feet of a railroad crossing. When parking on a hill, turn the wheels toward the curb when facing downhill, away from the curb when facing uphill with a curb, and toward the right shoulder when facing uphill without a curb; always set the parking brake.

Motorists must safely share public roadways with pedestrians, bicyclists, motorcyclists, commercial trucks, and public transit. Drivers must yield the right-of-way to pedestrians crossing within marked or unmarked crosswalks. Under Colorado law, motorists passing bicycles must allow at least three feet of clearance between the vehicle and the bicycle until safely past.

Under Colorado's Move Over Law, motorists approaching stationary emergency vehicles, law enforcement cars, tow trucks, or maintenance vehicles displaying flashing warning lights must safely vacate the lane closest to the vehicle or slow down significantly below the posted limit. Drivers must stop at least 20 feet from a school bus displaying flashing red lights, unless traveling in the opposite direction on a physically divided highway.

Colorado's steep mountainous terrain and severe winter storms require specialized driving techniques and equipment. When descending steep grades, drivers should downshift to a lower gear to let engine braking control speed, preventing brake overheating and failure. When two vehicles meet on a narrow mountain road where they cannot pass, the vehicle traveling downhill must yield and back up until the vehicle traveling uphill can safely pass.

Runaway truck ramps are emergency gravel paths located on steep mountain downgrades strictly reserved for out-of-control vehicles; never block or park on these ramps. During severe winter storms, Colorado enforces the Traction Law (Code 15 / Code 16), which mandates that all passenger vehicles have snow tires, mud/snow (M+S) tires, or four-wheel/all-wheel drive with at least 3/16-inch tire tread depth (or tire chains). Headlights must be turned on from sunset to sunrise, whenever wipers are in continuous use, and high beams must be dimmed within 500 feet of oncoming vehicles and 200 feet when following.

Colorado law establishes two distinct levels of impaired driving offenses: Driving While Ability Impaired (DWAI) at a Blood Alcohol Concentration (BAC) between 0.05 percent and 0.079 percent, and Driving Under the Influence (DUI) at a BAC of 0.08 percent or higher (or 0.02 percent for underage drivers). A driver with a BAC of 0.15 percent or higher is designated a Persistent Drunk Driver (PDD) and subject to mandatory Ignition Interlock Device (IID) installation.

Under Colorado's Express Consent Law, operating a motor vehicle anywhere in the state constitutes legal consent to chemical testing of your breath or blood if arrested for DUI or DWAI. Refusing a chemical test results in an automatic one-year license revocation for a first offense and designation as a Persistent Drunk Driver.

The Colorado DMV administers a demerit point system to track traffic convictions. Adult drivers (age 21 and older) face license suspension for accumulating 12 points in 12 months or 18 points in 24 months, while minor drivers under 18 face suspension for accumulating 6 points in 12 months. Point values for convictions include: 12 points for DUI or speed contests, 8 points for DWAI, 6 points for reckless driving, and 4 points for speeding 10 to 19 mph over the limit.

All motor vehicles registered in Colorado must maintain continuous liability insurance coverage with minimum policy limits of $25,000 for bodily injury to one person, $50,000 for total bodily injury per crash, and $15,000 for property damage (25/50/15). Vehicles must be registered annually in the owner's county of residence, displaying valid license plates and current year decals.
